A retrospective study of 46 patients with primary superficial bladder tumor was performed to identify the prognostic parameters which affect tumor recurrence. We examined 4 parameters such as stage, grade, size and number of tumor and each parameter was compared with recurrence rate respectively. The recurrence rate of stage Ta and T1 within 2 years was 33.3 % and 71% (p<0.05) and that of grade I, II and III was 40%, 60% and 100% respectively(p<0.05). Tumor recurrence was observed in 44% of patients with single tumor, 76.2% of those with multifocal tumors(p>0.05) and tumor size had no effect on tumor recurrence(p>0.06). Early recurrence rate within 1 year of grade I, II and III was 20%, 32% and 100% respectively(p< 0.01 ) but stage, number of tumor and tumor size were not correlated significantly with early recurrence rate within 1 year. A separate evaluation of the 4 parameters showed that stage and grade have a significant influence on tumor recurrence. Therefore more aggressive therapy and intensive follow-up should be considered for patients with high stage and high grade tumors.

BACKGROUND: Herpes zoster(HZ), caused by reactivation of latent varicella-zoster virus, is manifested by dermatomal distribution of skin rashes, acute pain and post-herpetic neuralgia by pathologic involvement of the sensory ganglia. Low-energy laser(LEL) deliver a small amount of energy without elevation of the tissue temperature. LEL is reported to have various biologic effects such as anti-inflammatory, analgesic, regenerative, antiallergic, immunocorrective, and antibacterial effects. OBJECTIVE: We attempted to evaluate the therapeutic effect of LEL on an acute phase of HZ. METHODS: A total of 60 patients with acute HZ were enrolled in the study. The control group(30 patients) received medications including analgesics, antihistamine, and topical care without LEL irradiation. The experimental group(30 patients) were irradiated with LEL daily for 7 days in addition to the same kinds of medications for the control group. The efficacy of LEL irradiation for HZ was assessed by analyzing changes in skin rashes, pain scores, and postherpetic neuralgia.

Fracture of the tibial shaft is one of the most common fractures of the long bones and frequently followed by malunion, delayed union and nonunion. We experienced the cases of further increase in the angulation after clinical union of the tibial shaft fractures treated by conservative method. So we analyzed 39 cases of tibial shaft fractures which were followed up from 12 weeks to 37 weeks after clinical union in adults. The results were as follows; l. 7 of the 39 cases(18%) showed the increase in the angulation, and all of them were male. 2. Increase in the angulation occurred more frequenlty in the comminuted fractures than simple fractures. 3. The increment of angulation was more marked in group of patients with higher angulation at the time of clinical union. 4. Increase in the angulation occurred more commonly in the cases not associated with fibula fracture than in the cases associated with fibula fracture. 5. Further increase in the angulation was less common in the cases in whom early weight bearing with PTB cast was started.

Chronic acquired hepatocerebral degeneration (CAHD) is a progressive or episodic neurologic syndrome that occurs occasionally in patients who have chronic liver disease or portocaval shunt. The clinical features of CAHD include action and postural tremors, generalized chorea, asterixis, myoclonus, dystonia, resting tremor, gait ataxia, and variable impairments of intellectual function. We experienced 2 cases of CAHD with unusual neurologic manifestations, which were hypokinetic parkinsonian symptoms. Both cases had a history of liver cirrhosis and the same symptoms. They had masked faces, cogwheel rigidiy in both wrists, slurred speech, tongue tremor, bradykinesia, and gait ataxia. They had normal mental status and no pathologic reflex. Brain MRI showed abnormal, increased signal on T1-weighted images in the globus pallidus and mesencephalon bilaterally. The hypokinetic parkinsonian symptoms disappeared when given doses levodopa.

PURPOSE: To compare the effect of nerve regeneration with infiltration of normal saline and nerve growth factor after vein graft to the resected sciatic nerve of rat. MATERIALS AND METHODS: Eighty Sprague-Dawley rats were divided into five experimental groups: orthotopic nerve graft as control group, inside-in vein graft with normal saline infiltration, inside-out vein graft with normal saline infiltration, inside-in vein graft with nerve growth factor infiltration and inside-out vein graft with nerve growth factor infiltration group. Animals of each group were sacrificed after electromyography at 2, 4, 8 and 12 weeks after operation. Also the light microscopy and transmission electron microscopy were performed to observe histologic change of grafted sites. RESULTS: This study demonstrates that autogenous vein graft serves as a conduit for nerve regeneration, and inside-out vein graft technique and nerve growth factor induce faster and more numerous axonal regeneration and earlier recovery of muscle power. CONCLUSION: Inside-out vein graft with nerve growth factor infiltration is supposed to be a promising technique to take the place of autogenous nerve graft.
